Asthma and thunderstorms

Thunderstorm asthma is a potentially dangerous mix of pollens, weather conditions and rain that can trigger severe asthma symptoms. People residing in metropolitan, regional and rural areas can be affected.

How does a thunderstorm cause asthma symptoms?

Thunderstorms cause a rapid increase in the number of triggers in the air such as pollens, mold and dust and changes in humidity and temperature. Breathing this air in can irritate the lining of the airway causing swelling and extra mucus to be produced. This causes the airway to narrow and triggers an asthma flare-up. These flare-ups may become severe very quickly.



Do you have to be allergic to pollens or grasses to experience thunderstorm asthma?


Thunderstorm asthma can affect anyone. In fact, during very severe storms, some people who have never been diagnosed with asthma may experience breathing difficulties.

If you have asthma, be alert to the potential dangers of thunderstorm asthma.
